Understanding RV Solar Power Systems Explained Simply

This tutorial breaks down RV solar installations into their most fundamental components, removing the intimidation factor that often surrounds renewable energy systems. The video walks through a practical, budget-conscious setup featuring four 100-watt panels, an MPPT charge controller with Bluetooth monitoring, and two lithium batteries—a realistic mid-range configuration that costs under $900. Rather than getting lost in technical jargon about mono versus poly panels or series versus parallel wiring, the host focuses on how the three main parts (solar panels, charge controller, and batteries) actually work together as a charging system.

This guide suits RV owners and van dwellers considering boondocking without generator noise or campground hookups, particularly those who feel overwhelmed by solar terminology or unsure whether a DIY installation is achievable. Whether you're parked in shade or full sun, the tutorial demonstrates both fixed roof-mount solutions and flexible portable panels that can be tilted toward the sun as needed.

What You Should Know Before Installing RV Solar

  • Installation difficulty: The most challenging part is running wires from the roof down to your battery storage bay; the actual electrical connections are straightforward once you understand the concept.
  • Waterproofing is critical: Use Dicor or similar sealant under all roof penetrations and screw holes to prevent leaks—don't rely solely on rubber washers.
  • Connection order matters: Always connect the charge controller to your batteries first, then connect the solar panels to the charge controller. Never reverse this sequence.
  • Fusing and breakers: Install a fuse or breaker on both the solar input side and the battery output side of your charge controller to protect wires and equipment.
  • Choose an MPPT controller that scales: Select a 40–50 amp unit compatible with multiple battery chemistries (lead-acid, LiFePO₄, lithium) so your system can grow without replacement.
  • Plan for expansion: Size your wiring appropriately from the start if you might add panels later; running new wire twice costs more time and effort than installing it once.
  • Portable panels as backup: Adding two 100-watt tiltable panels that can be deployed in shade provides flexibility and doesn't require routing additional permanent roof wires.

Common Questions About RV Solar Installations

Is solar installation really doable as a DIY project?

Yes. The video demonstrates that understanding the three main components (panels, charge controller, batteries) makes installation much less intimidating. The hardest part is physically running wires through your RV, not the electrical connections themselves. The rest involves bolting brackets to your roof, connecting three wired sections, and adding fuses for safety.

How much power will a four-panel 400-watt system actually produce?

On a clear sunny day without tilting the panels, expect between 20 and 24 amps, which translates to roughly 280–340 watts. This varies based on season, angle, and sun intensity. The video shows real-time monitoring via the charge controller's app, so you'll know exactly what your panels are producing at any moment.

What if my RV is parked in shade?

The video demonstrates having two portable 100-watt panels that can be removed from storage, tilted toward the sun, and connected to the same system. This flexibility lets you supplement roof-mounted power without permanent roof modifications or worrying about shaded parking spots.

Do I need a battery monitor to use solar?

No, but the video shows using one with a shunt (a device that measures battery current). If you don't have a battery monitor, you simply connect the charge controller's negative wire directly to the battery's negative terminal instead of routing through a shunt.

What happens if I hook up the panels before connecting the charge controller to the battery?

The video emphasizes always connecting the battery first, then the panels. Connecting panels before the charge controller has a battery attached can damage the controller. The correct sequence is battery to controller, then panels to controller—using a breaker lets you safely make that final panel connection.

Justin’s Take

This video genuinely demystifies RV solar by stripping away the confusing terminology and showing that a working system doesn't need to be complicated. The host's willingness to walk through his actual setup—including mistakes he avoided like trusting only rubber washers—gives you real confidence that this is doable without an electrician. His emphasis on planning for future expansion rather than building the ultimate system day one makes solar feel approachable rather than overwhelming.

What I appreciated most was the practical sequencing advice: connecting battery first, then controller, then panels. That single detail prevents damage and keeps the focus on making safe, working connections instead of worrying about specs. If you've been sitting on the idea of adding solar to your rig, this tutorial removes the last excuse to put it off.

Description

RV Solar is not as difficult as it might first seem. When you can understand RV electrical in the roles they play it is easier to understand how it all works together. This is as basic as you can get to understand Solar for your RV. RV Solar is just another way to charge your batteries even while boondocking.

I don't know about you but I still find it absolutely amazing that you can have your RV sitting in the Sun pulling power harvesting power from the Sun just simply amazing how's it goin welcome to another all about RVs today we're gonna be looking at a simple solar setup talking about how solar really is simple

oftentimes it can get confusing with so many different things of what types of panels mono versus poly versus flexible versus rigid versus MPPT versus PWM there's a lot of things out there so we have a very simple solar kit and I thought I would share it with you guys Solar can be a bit intimidating and

somewhat overwhelming so I hope simplifying it will help some out there that Sun is actually getting intense right now so let's head inside and we'll talk about just how simple solar is because it's really just another way to charge your batteries a typical solar setup is going to have a few main

components so let's start with the solar panels that are on top of the RV and then that's connected to your charge controller and the charge controller that is then going to connect to your batteries you're gonna put some fuses and some breakers on each side of that charge controller to protect your

equipment and your wires and that's really the basic gist of a solar setup to keep things working properly and to keep it safe I do have to admit it is more complicated or difficult to install it than it is to understand the concept but first you want to understand the concept so you can install a system so

we'll look at our system and how its installed so you can kind of get an idea what it takes to install just an average solar setup for your rig the kit that we have costs just under nine hundred dollars and it has four 100 watt panels that are up on the roof of the RV it came with the wire the mounting hardware

it also has the MPPT charge controller that has bluetooth so you're able to log into it and see what what the panels are producing how much is going into your batteries it's it's handy to be able to have that and then it has the wires and a few to do all of that safely and on the

battery side of things we have to battleborn batteries so we have two lithium batteries it's not a crazy huge system it's actually very average for what people install on their RVs when you plan to go solar there's some things you can do so you can plan for the future you don't have to have this big

system all at once right from the beginning so what does this system produce so if you pull up the app it'll tell you how many watts the system is producing so on a nice sunny day we can be getting usually we don't tilt our panels or anything we'll be pulling in between 20 to 24 amps

which is around 280 watts to about 340 watts somewhere in that range installing a system like this really isn't difficult I'd say the most difficult part is actually just running the wires getting them from the roof of the RV down to say one of the areas the storage areas where you might have your charge

controller or whatever Bay you're trying to get it to that's usually the hardest part is just running the wires so on our setup I just started by putting the mounting hardware right onto the solar panels they just bolt right on the the kit that came with this it's really a no frills kind of a bracket but it works

well and then it's just simply getting the panel's up there and laying them out and marking them where you want them to go and where you would like them on your roof I like to mark where each bracket is going to be in each screw hole that way I can get the Dicor underneath there so that when I'm putting my screw

through it pulls it down into that membrane the dike or product so it just gives it a nice tight seal in the box for the brackets there's actually the screws to be able to screw the panel's down to the roof even comes with a little rubber washer I wouldn't trust that rubber washer so I made sure I had

a tube of Dyke or so that I could cover up any of those penetrations because I don't want any leaks at all from installing solar we did buy an additional box to be able to get those wires from the roof down below and we actually positioned it for ours this is different than probably anybody else's

but we put it where we had an old solar setup so I just had to get it to where those wires were because I knew the gauge of that wire was thick enough to a accommodate the wires that I needed for this solar setup and of course I'll have a link down in the description to all the components that we use to be able to

make this system work we actually just used an MC 4 connector inside this box I know that that's waterproof but it got us to the existing wires that were there and we were able to make it all watertight for being able to come down into the RV just a quick side note you might see that these

panels are wired and parallel right now I'm doing that I'm experimenting and playing around with a few things I can wire this in series or parallel that's a different subject I actually have a video on some of that but from here we're going to take our wires from the panel's and we're gonna go down to a

fuse I called it a fuse but it's actually a breaker I like this I added this to the system because just with the press of a button I'm able to disconnect the solar panels from the charge controller and not have any power input coming from that so it's extremely simple and easy because you don't want

to hook up your charge controller to your panels until you've hooked it up to a battery that's usually the procedure on how you hook things up first your charge controller is going to connect to your batteries and then you're going to connect your solar panels to the charge controller so connecting the batteries

to the charge controller is pretty simple we're gonna have a fuse in between there so on the positive side coming from the charge controller would go to a fuse it's kind of hard to see where we have it mounted on ours and from the fuse we're gonna go to the positive side of the battery and on the

negative side since we have a battery monitor we go from the shunt to the charge controller if we didn't have a battery monitor with a shunt we would just go straight to the battery once you connect the charge controller to the battery it's actually going to power on it's gonna bring up the display and then

you can finish hooking it up from the solar panels to the charge controller you can turn on that little breaker be able to make that connection and then you'll see what is coming from the the panels and being able to go through to your batteries it really is that simple to install solar on your RV we will be

covering a lot of those other topics about sizing and different types of panels and flexible we're gonna cover all that but I just wanted to cover the basics of solar because it is really simple now let me give you some tips if you're wanting to get into solar but you have the budget or the time to be able

to get into the system that you hope to have someday so I would recommend getting a charge controller like an MPPT one that can handle different types of battery chemistry get like a 40 or a 50 amp charge controller that way your system can grow and you're not stuck it's a 15 amps or something like that I

would get one that can handle the the lead-acid if that's what you have now and maybe someday you hope to be able to go to a GM or lithium this one that we have it can do all the different types of battery chemistry which comes in handy charge controller that we have is actually a hundred and sixty-five

dollars just to give you an idea and for me I know this is a must but I really do like this one that has the app and it shows you a lot of the information that way you can be informed if you want to grow your system or if you just need to change a few things it really does help out it shows you the wattage that's

coming from your solar panels currently what's being sent to the charge controller what's actually making it into your batteries it really is nice to be able to have all that information in a nice easy place right at your fingertips so for us we have the four panels on the roof but we actually have

room that we added to 100 watt panels that we can pull out and we can tilt them towards the Sun say if our rig is parked in the shade and we hook it into this system it can handle that and it works well so if the rigs in the shade we can still get solar coming into the rig and along that same line of thought

if you're thinking about expanding the system on your roof in the future just size that wire appropriately that you're running from the top to the bottom because you don't want to have to do that twice I hope that this helps simplify solar for some and makes it a little less intimidating if you want to

look at an inverter or just using it as your normal DC loads you have lots of options of being able to use the energy from your batteries but solar is just an amazing way that you can put power into them without having to run a generator or plug-in or any of that kind of stuff so that's the beautiful part about solar
